[PATCH master 4/4] Documentation: migration-guide: add note about ZynqMP OP-TEE

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

This popped up looking through AI-detected relevant device tree changes.
Assuming OP-TEE unconditionally was not a good idea anyways, so we won't
work around it and will just document this.
